Abstract Recently, radiomic texture quantification of tumors has received much attention from radiologists, scientists, and stakeholders because several results have shown the feasibility of using the technique to diagnose and manage oncological conditions. In patients with hepatocellular carcinoma, radiomics has been applied in all stages of tumor evaluation, including diagnosis and characterization of the genotypic behavior of the tumor, monitoring of treatment responses and prediction of various clinical endpoints. It is also useful in selecting suitable candidates for specific treatment strategies. However, the clinical validation of hepatocellular carcinoma radiomics is limited by challenges in imaging protocol and data acquisition parameters, challenges in segmentation techniques, dimensionality reduction, and modeling methods. Identification of the best segmentation and optimal modeling methods, as well as texture features most stable to imaging protocol variability would go a long way in harmonizing HCC radiomics for personalized patient care. This article reviews the process of HCC radiomics, its clinical applications, associated challenges, and current optimization strategies.

Abstract.Cabanillas-Saez A, Schalper JA, Nicovani SM, Rudolph MI. Characterization of mast cells according to their content of tryptase and chymase in normal and neoplastic human uterine cervix.Mast cells (MC) have been associated with diverse human cancers. The primary function of these cells is to store and release a number of biologically active mediators, including the serine proteases tryptase and chymase. These proteases have been closely related with angiogenesis and tumor invasion, two critical steps during tumor progression. In the present work we analyzed the presence of MC in human uterine cervix from both normal and neoplastic tissues by using metachromatic, immunohistochemical, and enzymohistochemical staining. Tryptase-positive (MCT)– and tryptase/chymase-positive (MCTC)–mast cells were found in both normal and neoplastic tissues. The phenotype predominantly expressed in normal tissues as well as in benign and malignant lesions of the uterine cervix was the MCT. The total number of MC remained constant through the different stages of malignant transformation (cervical intraepithelial neoplasia grade 1–3) but a significant increase in the invasive carcinoma (IC) group was observed, this increase being mainly due to the MCT phenotype. Furthermore, we detected abundant MCT but not MCTC infiltrating tumors in sections of IC. Regarding the potent angiogenic properties described for tryptase, these findings suggest that in advanced stages of malignancy the significant number of MCT distributed within the cervical tissues could provide an effective mechanism to create the abundantly vascularized microenvironment required for tumor cells to proliferate and disseminate.

3D Surface Texture

Surface characterization technologies are generally sorted into two categories: noncontact and contact-based technologies. Among these technologies, no one can stand out to simultaneously and rapidly measure both surface patterns/textures and mechanical properties such as softness, friction, and mechanical impedance. In this paper, we have addressed this problem and developed a multifunctional and portable surface texture sensor through combination of both contact and noncontact optical surface profiling mechanisms. The developed sensor relying on an optomechanical principle can be efficiently used for quantitative characterization of surface texture properties including 3D texture pattern, roughness, and even mechanical properties like softness, etc. As one of the important applications, we have used the sensor to measure and analyze texture properties of extensive automotive interior leather sample surfaces. The results demonstrate that the sensor can effectively assist the interior designer to quantify and classify essential texture features of automobile interior surfaces.
